....l inks (op tic fi bers) l ong and var iab le delay paths (satellite links) lossy links (wireless networks) asymmetr ic paths (hybrid satel lite networks) and others are becoming w ide l y embedded in the Internet . Many works have studied by experimentation [1 4] analytical modeling [5 8], and simulation [6, 9 11] the performance of TCP in this new environment. Most of these works have focused on a particular environment (satellite networks, mobile networks, etc. They have revealed some problems in the operat i on o f TCP. Long propagation de lay and losses on a satellite l ....
....where ssthresh is set to a default value. As an example, it has been proposed in [11] to set the threshold at the beginning of the connection to the BDP in order to switch to CA before the occurrence of losses. This will not work if the buffer is smaller than half the BDP (half T 2) In [5] we study the problem of early buffer overflow during SS for multiple routers in tandem. We show that, due to the high rate at which packets are sent during SS, queues can build up in routers preceding the bottleneck as well. Buffers in these routers must also be well dimensioned, otherwise they ....

....applied, a typical html page might be downloaded with approximately a 60 gain of HTTP1.0 [10] Another study case presents a TCP Analysis algorithm: Slow Start which adapt the size packet in order to optimise the bandwidth. However the gain isn t guaranteed and worse results can also be obtained [1], for instance if the buffer sizes are not well dimensioned. The second current idea addresses the source code modification in order to reduce the latency delays. In [20] authors present an implementation of the TCP stack in the user space and IP in the kernel space. By placing the TCP protocol ....
